Nvidia GPUs power the vast majority of gaming PCs, but for more integrated game systems like consoles and handhelds, AMD's ability to offer tightly integrated Ryzen CPUs and Radeon GPUs has earned it many customers (and lots of revenue). The most notable of these is Valve's Steam Deck, which combines a Zen 2-based CPU and RDNA 2-based GPU cores to provide passable performance for most games.

Though AMD designed the Steam Deck's chip exclusively for Valve, today, the company is announcing a pair of Ryzen chips aimed at the growing number of Steam Deck-esque handheld PCs from other companies. The Ryzen Z1 and Z1 Extreme (respectively) combine 6 or 8 Zen 4-based CPU cores with 4 or 12 RDNA 3-based GPU cores, using AMD's latest architectures and a 4 nm manufacturing process to outrun the Steam Deck's APU.
